Application filed November 2 1-, 18-24:.

In the case of the devices hitherto known for threshing, grinding orpulverizing the work is done by friction or beating and consequentl-ysuch devices have all the d1sadvantages connected with this kind ofwork, of which the most serious consist in the fact that 1. The materialto be worked absolutely must be completely dry;

2. The output of such devices, in comparison with the power consumed, isvery small.

The process forming the subject-matter of the present invention and theapparatus for carrying it out remove the abovementioned disadvantages ina simple and appropriate manner by the fact of their being based oncentrifugal force, owing to which the work is simplified and proceedsquite independently of the condition of the materials.

One constructional form of such an arrangement is illustrated in cnosssection in Figure 1. Figure 2 shows partly an elevation and partly asection on the line AB in Figure 1. Figure 8 is an elevation, and Figure4 a plan. In Figures 5, 6, 7 and 8 details are illustrated.

In the constructional form illustrated the present invention consists ofa drum 1 provided on its inner surface with teeth 18 (Figures 1 and 2),the said drum being secured in a casing 2, and of a disc 3 fastened inthe interior of the drum 1 on the rotatable shaft 4 which does not passthrough the centre driven in any desired manner, for exam ple by meansof a belt drive, the discs 3 dividing the drum 1 into two chambers, 9and 10. The chambers 9 and 10 are of different diameters, and the largerchamber, 10, is pro vided in the lower part with sieves inserted ingrooves 7. The two parts of the drum 1 are connected to one another byscrews 8, which serve at the same time for fastening the drum 1 to thecasing 2.

The disc 3 is arranged in the one chamber 10 in such a manner that itsedge lies in the. vicinity of the second chamber 9. On both sides of thediscs 8 are arranged grippers secured with screws 12, there being, inthe smaller chamber, three of the said grippers, 11, which do not reachthe centre of the ad mission aperture 13, and also the grippers 11*, thenumber of which depends on the di- Serial No. 751,998.

mensions of the apparatus as a whole but a 11, the numberof which isalso dependent upon the dimensions of the apparatus, and which arelikewise equipped with attachments secured with screws 16 and havingsharp points 15, the ends 17 of which pass over the disc 3 into thechamber 9. The grippers 11 are erected at a definite angle, in order toprevent the apparatus from becoming choked with the material.

The method of working of the apparatus is as follows The shaft 4, andwith it the disc 3, is set in rapid rotation at about 1200 to 1500revolutions per minute, and the material is then admitted to theapparatus through the inlet 13, where it is set in incipient rotation bythe grippers 11 and consequently arrives at the grippers 11 which impartto it quicker motion, in which'case for example the plants separate forthe most part from the husks or shells, and the entire mass rotating isseized by the ends 17 of the spikes 15 and thrown over the disc 3 intothe chamber 10, where by the action of the grippers 11 it is set in veryra id rotation, with which there co-operates t e eddy of air arisinghere by virtue of the fact that the disc 3 is not secured at its centre.Under the action of the centrifugal force caused by the rapid rotationand of the air eddy the plants are for example separated from theshells, which in this case for the most part remain whole.

The working space may if desired be enlarged or diminished according tothe kind of work required, which may be simply effected by sliding itstwo parts towards or away from one another, by means of screws forexample, which may be applied to the sides of the drum 1, and which arenot shown in the drawing.

Uf course the apparatus may be designed with different constructionalmodifications wthout going outside the bounds of the inventiondescribed.

hat I claim is 1. Apparatus for disintegrating plants and othermaterials including a casing, a

drum secured to said casing and having two internal diameters, arotatable shaft passing through the axis of the drum, a disc secured tosaid shaft and located within the drum adjacent the juncture of the twodiameters so as to divide the interior of the drum into two differentlydiametered chambers, grippers arranged on one side of the disc andwithin the small chamber for successively imparting an incipient and aquick rotation to the material, and other grippers secured to the otherside of the disc and within the large chamber and extending across andpartially into the small chamber for seizing the material and forfacilitating the transfer of the material over the edge of the disc andmto the large chamber, substantlally as and for the purposes set forth.

2. Apparatus as claimed in claim 1, wherein the grippers in the largechan'iber are fitted to the drum at a predetermined angle to avoid theclogging of the material and sharp pointed attachments fitted on theends of said grippers and disposed at angles to the main portion of thesaid grippers so as to extend across the periphery of the disc.

In testimony whereof I have signed my name to this specification.
